"battlepage_03.tga" from \bi\data\ui\[culture]\interface; copy/paste over the equivalents in the appropriate EB folders (ie. \EB\data\ui\[culture]\interface). Mentioned in the "EB with BI.exe" thread in the Unofficial Mods subforum IIRC.

...to quote myself. Albeit I wasn't able to find where it was mentioned with a cursory search.
